IMPROVEMENT IN COAL-S TOVES.

which- Figure l is a perspective view of the stove. Fig. 2 'isa vertical section in the direction of the lines was in Fig. 1. Fig. 3 is a vertical section in the direction of the lines :10 a," in Fig. 1'.

Like letters of reference denote like parts in theseveral views.

My improvement in this class of stoves relates toiconstructinga stove for the purpose -of obtaining the more perfect combustion of fuel and consumption of the inflammable gases and have the greatest amount of surface for the radiation of heat.

A represents the body or drum of the stove that contains the fire-box; B B, columns orflues on each side, that communicate with chambers in the top 0 and base D of the stove. The

entire stove is susceptible of other forms and configurations different from that represented in the drawings. a

The internal structure of the stove is shown in Figs. 2 and 3, in which E is the fire-box, extending up from the base D till about the center of the drum A, the back part being curved up higher, as represented. The fire-box tapers gradually toward the top, being a little narrower across the 11 per end than at the base, leaving a space be ween it and the outer casing. In the rear of the fire-box vthere is a hotairchamber, F, that extends down into the ashpit F. In front of the chamber F and rear of the fire-box, at the lower end, there is a grate, f, through which there is a draft into the firebox.

H is a corrugated plate, that is placed in a space, a, between the upper back edge of the fire-box and perforated plate G of the chamber F, and extends about half-way round the firebox, and being corrugated the same radiatingsurface is obtained as if the plate were plain and extended all the way round. The corrugations admit the heated air from the eh amber Specification forming part of Letters Patent No 48,252, dated June 20, 1865.

F into the tire box in the desiredmanner, and

said plate will resist the influence of theheat better than if it were plain. Airis also admitted through the perforated plate G into the fire-box.

I and J are draft or induction pipes in ,the rear of the stove, that extend from the outside and enter the chamber F, the pipe J a short distancebelow the fire-box, so as to produce the desired draft, and the pipe I above, as shown in Fig. 3, designed especially to furnish the hot-air chamber with air. Over the outer end of the pipe J ,in the rear of the base of the stove,

there is a door, L, with a damper, l, in it, by which the draft is regulated. v

b is a vibrating grate between the fire-box and ash-pit.

'H' is a door in front that opens into the ash-- .pit, and is provided with a damper, h, by which draft can be produced. from the frontof the stove. The ashes are removed through this door.

B is a door in the body of the stove, by which the fire-box is provided with fuel. It will be observed from the arrangement of the pipe J, grate f, 8m, that the draft is prineipally at the rearor the stove; consequently the fuel will ignite more rapidly and burn from therear to the front of thefire-box. The greatest heat from the more rapid combustion of the fuel bein'g'at the rear, the smoke and unconsumed inflammable gases will rise principally from the front and pass up through the fire-box in the direction of' the arrows d in Fig. 3, and

in passing over they come in contact with the more intense heat rising from the rear of thefire-box, and also with the hot air from the chamber F through the corrugated and perforated plates, admitting sufficient oxygen to cause the smoke and inflammable gases to be more perfectly consumed. The entire body of heat then passes down through a diving-flue, a, in the rear of the stove, around the hot-air ehamberF, round the pipes I and J, heating them,into a chamber, L, in the base D of the stove, which extends around the rear and sides of theash-pitF. From this chamber it ascends through the columns or pipes B B into the chamber 1? in the top of the stove, as indicated by the arrows, and out through" the pipe B. Thus the heat from the fire-box, arising from the burning of the fuelin the manner described,

producing the most perfect combustion. of the fuelandinflammablegases,canbcdisseminated through the entire stove and pipes, presenting so much surface from which heat can be radiated that will keep a room at the desired temperature with the least amount of fuel.

By means of a damperyp, in the top of the stove there canbe a direct draft through the body of the stove when desired.

The air-chamber F .being next the hottest part of the fire-box, and a constant current of hot air passing down round on the outside, the air in the chamber becomes very much heated, thereby-causing combustion of the gases with which it comes in contact-the object for which it is principally designed-and a great amount of heat is saved in this way. The hot air surrounding the pipes I and J also heats the air passing through them before it reaches the chamber F, heating the air that produces the draft before it enters the fire-box. The induction-pipe I supplies the chamber F with sufficient air, so-as to consume the gases that may be generated in the fire-box when the draft is shut efl' from below. The back-draft, carrying the heat from the front to therear of the stove, leaves the mica in the door clear and prevents it from being darkened by the smoke and soot.

The induction-pipes I andJmaybe arranged at the sides of the stove, in connection with a chamber similar to F or without said chamber, but I prefer the arrangement as set forth.

The principle involved in the construction of thisstove may be employed in hot-air and smelting furnaces.

What I claim as my improvement, and desire to secure by Letters Patent, is

I 1. So constructing the fire-box that the fuel is consumed first in the rear of the same when said chamber is arranged in relation to the ash pit F, air-chamber F, and dampers L and H substantially as set forth.

2. Arranging the fire-box E in front of the stove. in combination with the hot-air chamber F, the draft-pipe J, and diving-flue a, as and for the purpose set forth.
